Good evening/morning all!
For a service I develop, I'd like to implement jumbo frames on all network
adapters available on the servers running the app to facilitate better
throughput, except for the loopback one using augeas.
Details regarding my setup - RHEL8, puppet 7 and the last version of
herculesteam/augeasproviders_shellvar. Cannot upgrade to the successor of
the module for complexity reasons. So far I've managed to identify and
trace all dependencies needed to use the
herculesteam/augeasproviders_shellvar.
My questions to you are
1. Do I need to do mandatory install of augeas , augeas-devel and
augeas-lib rpms on the target/test host to have my puppet code work or this
is a step for debugging purposes / testing before actually writing the code
that puppet executes
2. Can you give me some examples how to filter out the loopback adapter
from the context and apply the change if the MTU value is not present or
missing in the ifcfg-X file ?
Sample skeleton
class tuning {
augeas { 'set_jumbo_frames'
lens => 'Shellvar.lns',
context =>
changes => [
'set MTU 9000',
],
onlyif =>
notify => Exec['service network refresh']
}
}
}
Many thanks in advance for the pointers!
